返回值

Array of meta data about opcode cache 或者在失败时返回 FALSE

The array returned by this function contains the following elements:

total_cache_uptime - total time in seconds that the opcode cache has been active
total_file_count - total number of files that are currently in the opcode cache
total_hit_count - number of times the compiled opcode have been served from the cache
total_miss_count - number of times the compiled opcode have not been found in the cache
is_local_cache - true is the cache metadata is for a local cache instance, false if the metadata is for the global cache
file_entries - an array that contains the information about all the cached files:
- file_name - absolute file name of the cached file
- add_time - time in seconds since the file has been added to the opcode cache
- use_time - time in seconds since the file has been accessed in the opcode cache
- last_check - time in seconds since the file has been checked for modifications
- hit_count - number of times the file has been served from the cache
- function_count - number of functions in the cached file
- class_count - number of classes in the cached file

范例

Example #1 A wincache_ocache_fileinfo() example


<pre>
<?php
print_r(wincache_ocache_fileinfo());
?>
</pre>

以上例程会输出：

Array

    [total_cache_uptime] => 17357
    [total_file_count] => 121
    [total_hit_count] => 36562
    [total_miss_count] => 201
    [file_entries] => Array
        (
            [1] => Array
                (
                    [file_name] => c:\inetpub\wwwroot\checkcache.php
                    [add_time] => 17356
                    [use_time] => 7
                    [last_check] => 10
                    [hit_count] => 454
                    [function_count] => 0
                    [class_count] => 1
                )
            [2] => Array (...iterates for each cached file)
        )
)
